Those who are trying to build this type of heating appliance should know how to choose the right thickness of vermiculite board for a fireplace so that it works efficiently and safely. For advice, see the following article
Choosing the right thickness of vermiculite slab for a fireplace is very important for its proper operation and safety. Heat-resistant slabs should be selected according to the type of fireplace and its purpose. For example, a 25 mm vermiculite slab would suit a fireplace used occasionally, for recreational purposes. For a fireplace used regularly as a source of heat, a customised vermiculite slab made in 30 to 40 mm thickness is useful. These types of products can be found in the renowned Vitcas brand shop. For cookers and boilers where the temperatures are considerably higher, heat-resistant slabs as thick as 50 mm or more will be necessary. The size of the fireplace and the recommendations of its manufacturer also play a role in the selection of the slabs.
What is the importance of vermiculite board thickness in fireplace insulation?
It is worth remembering that the higher the temperature in the combustion chamber, the thicker the vermiculite board should be. High temperatures can cause thinner slabs to wear out more quickly, leading to a loss of their insulating properties and potential damage to the fireplace structure. Thicker and higher density heat resistant slabs, provide even insulation and good protection against heat loss. If in doubt, consult an experienced chimney sweep who can help you choose the right thickness of slabs for your fireplace. When you order made-to-measure vermiculite slabs from Vitcas, which are heat-resistant and have good insulating properties, you can be sure of a good purchase.
Recommendations for the thickness of vermiculite slabs
Choosing the right thickness of vermiculite slab for your fireplace is crucial to its performance and safety. For recreational fireplaces, a 25mm vermiculite slab is sufficient, while for everyday use it is worth considering a thickness of 30-40mm. For cookers and boilers where temperatures are higher, heat-resistant slabs of 50mm or more are recommended. In addition to the thickness, the insulating properties are also important – a made-to-measure vermiculite slab allows for a perfect fit to the structure and maximises thermal efficiency. It is also worth considering the fireplace manufacturer’s recommendations and consulting a specialist. If you are looking for robust high-temperature insulation materials, check out the range on the Vitcas website and choose a product to suit your needs!
